In the description of this application, "a plurality of" means two or more, unless otherwise specifically defined.

[0044] Please refer to Figures 1 to 3 together. Now, the humidifier provided by the embodiments of this application will be described. The humidifier includes a water tank assembly 100, a humidifying filter screen 200, an air outlet housing 300, a machine base 500, and a fan assembly 600; the humidifying filter screen 200 is disposed below the water tank assembly 100; the air outlet housing 300 covers the humidifying filter screen 200 and is connected to the water tank assembly 100; an air outlet hole 301 is provided on the side wall of the air outlet housing 300; the machine base 500 is located below the air outlet housing, and a plurality of air inlet holes 511 are provided on the machine base 500; the fan assembly 600 is disposed in the machine base 500 and is located below the humidifying filter screen 200.

[0045] Compared with the prior art, for the humidifier provided by this application, in this embodiment, the humidifying filter screen 200 is disposed below the water tank assembly 100, and the water in the water tank assembly 100 can be controlled to flow downward to spray the humidifying filter screen 200, avoiding the risk that the humidifying filter screen 200 is easily yellowed and bacteria are bred due to being soaked in water for a long time, improving the service life of the humidifying filter screen 200 and the safety of humidifying air. The air outlet hole 301 is provided on the side wall of the air outlet housing 300, and the humidifying filter screen 200 is disposed close to the air outlet hole 301; the humidifying filter screen 200 is not affected by the water tank assembly 100 and has a large humidifying area, which can ensure a stable humidifying amount; moreover, air can directly pass through the humidifying filter screen 200 and be blown out from the air outlet hole 301, reducing the air path and thus reducing the loss of air volume and improving the humidifying efficiency.

[0046] It can be understood that existing humidifiers generally blow air from the top of the humidifier. For example, an air outlet channel is provided in the middle of the water tank or between the water tank and the side wall of the machine. With such a setting, obviously, the flow path of air inside the humidifier will be increased, and at the same time, the structure of the water tank will become complicated. Therefore, in this embodiment, the air outlet housing 300 is disposed below the water tank assembly 100, and the air blown by the fan assembly to the humidifying filter screen is directly blown out from the air outlet hole of the air outlet housing 300, which can reduce the air flow path and air loss; the water tank assembly 100 is disposed at the top of the humidifier, and no air outlet channel needs to be provided inside the water tank assembly 100, optimizing the structure of the water tank assembly 100 to the greatest extent and making the water tank assembly 100 more concise.

[0047] In this embodiment, the fan assembly 600 is disposed below the humidifying filter screen 200. After the dry air passes through the fan assembly 600, it then passes through the humidifying filter screen 200 to humidify the air. Since the air passing through the fan assembly 600 is dry air, it is beneficial to moisture-proof the fan assembly 600 and improve the service life of the fan assembly 600.

[0048] In this embodiment, the air inlet hole 511 can be provided on the side wall of the machine base 500 or on the bottom of the machine base 500; the box body 101 can be integrally formed with the air outlet housing 300 or connected by screws. When it is necessary to replace or clean the humidifying filter screen, the air outlet housing 300 can be lifted while picking up the water tank assembly 100 to reduce the operation steps for maintaining the entire humidifier. The machine base 500 can be detachably connected to the air outlet housing 300. For example, magnetic connection can be used to achieve quick assembly and disassembly of the machine base 500 and the air outlet housing 300.

[0049] In another embodiment of the present application, the machine base 500 and the air outlet housing 300 can also be integrally formed. The air outlet housing 300 is detachably connected to the water tank assembly 100. For example, magnetic connection can be used to achieve quick assembly and disassembly of the water tank assembly 100 and the air outlet housing 300.

[0050] In one embodiment of the present application, please refer to Figure 1 and Figure 3 , the water tank assembly 100 includes a box body 101 and a valve 103; a water outlet is provided at the bottom of the box body 101; the valve 103 is disposed at the water outlet for controlling the opening and closing of the water outlet.

[0051] In one embodiment of the present application, please refer to Figure 1 and Figure 3 , the humidifier further includes a water distribution tray 102. The water distribution tray 102 is located below the box body 101. As Figure 7 shown, a plurality of water outlet holes 122 are provided on the water distribution tray 102, and the humidifying filter screen 200 is disposed below the water outlet holes 122.

[0052] In this embodiment, by providing the valve 103 at the water outlet of the box body 101, the water in the box body 101 can be actively controlled to flow into the water distribution tray 102, and then the humidifying filter screen 200 is watered through the plurality of water outlet holes 122 on the water distribution tray 102. While achieving uniform water distribution around, it also avoids the humidifying filter screen 200 being soaked in water for a long time; using the valve 103 to actively control the water flow rate reduces the noise during operation compared to the existing technical solution of using a water pump to suck the water from the bottom water tank to the top and then wet the humidifying filter screen.

[0053] Specifically, the humidifying filter screen 200 is cylindrical, and a plurality of water outlet holes 122 are circularly distributed. The positions of the plurality of water outlet holes 122 correspond to the positions of the circular ends of the humidifying filter screen 200.

[0054] In this embodiment, please refer to Figure 1 , a lid 111 can also be provided on the top of the box body 101 to facilitate users to add water; the box body 101 is located at the top of the entire humidifier, with a more concise structure and is also convenient for cleaning the box body 101.

[0055] In an embodiment of the present application, please refer to Figures 3 to 5 , the humidifier further includes a translation driving member 104; the translation driving member 104 is located below the valve 103, and the translation driving member 104 can drive the valve 103 to move up and down to open or close the water outlet.

[0056] In this embodiment, the valve 103 is driven by the translation driving member 104 to move to achieve the purpose of controlling the opening and closing of the water outlet. This can not only make the movement of the valve 103 stable and with low noise, but also can accurately control the water output.

[0057] Specifically, the valve 103 can adopt a push rod, and a rubber ring can be sleeved on the contact part between the push rod and the water outlet to improve the sealing performance when the push rod plugs the water outlet and avoid water leakage from the box body 101. The translation driving member 104 can adopt a solenoid valve, and the rod of the solenoid valve is moved up and down by energizing and de-energizing it.

[0058] In an embodiment of the present application, please refer to Figure 6 , a water flow groove 121 is provided on one side of the water distribution tray 102 facing the humidifying filter screen 200, and the water outlet holes 122 penetrate through the water flow groove 121.

[0059] In this embodiment, the bottom of the water distribution tray 102 abuts against the top of the humidifying filter screen 200. By providing the water flow groove 121, the water outlet holes 122 can be kept at a certain distance from the humidifying filter screen 200, avoiding the bonding of the water outlet holes 122 and the humidifying filter screen 200 to generate a water film and blocking the water outlet holes 122, and improving the smoothness of the water outlet holes 122.

[0060] In an embodiment of the present application, the depth of the water flow groove 121 is greater than or equal to 2 mm. In this embodiment, it is preferably that the depth of the water flow groove 121 is 2 mm, that is, the water outlet holes 122 and the humidifying filter screen 200 can maintain a distance of at least 2 mm. Such a setting can not only keep the water outlet holes 122 smooth, but also make the overall structure more compact, which is beneficial to the miniaturization design of the humidifier.

[0061] In an embodiment of the present application, please refer to Figure 6 and Figure 7, the water diversion tray 102 includes a water diversion part 123 located in the middle, a water drainage part 125 located at the edge, and a diversion part 124 connecting the water diversion part 123 and the water drainage part 125; the water diversion part 123 protrudes relative to the water drainage part 125, the diversion part 124 is inclined, and the water outlet holes 122 are arranged on the water drainage part 125.

[0062] In this embodiment, by arranging the water diversion part 123 and the diversion part 124, the principle of "water flowing to lower places" can be utilized. The water diversion part 123 is located below the water outlet. After the water in the box body 101 flows out, it is diverted to the water drainage part 125 through the water diversion part 123 and the diversion part 124, and then flows out through the water outlet holes 122 of the water drainage part 125, and finally flows onto the humidifying filter screen 200, thereby achieving the effect of wetting the humidifying filter screen.

[0063] In an embodiment of the present application, please refer to Figure 6 and Figure 7 , the water diversion part 123 is provided with a raised wall 126, and the raised wall 126 encloses a water diversion groove, and the water diversion groove is arranged towards the water outlet; the raised wall 126 is at least provided with two water diversion notches 127.

[0064] Specifically, the water diversion groove is cylindrical, two water diversion notches 127 can be provided, and the two water diversion notches 127 are distributed oppositely along the side wall of the water diversion groove, and the two water diversion notches are spaced 180°. The water in the water diversion groove can flow to the water drainage part in the left - right direction, making the water drainage more uniform. The number of water diversion notches 127 can also be three, four, five, six, etc.

[0065] In this embodiment, by arranging the water diversion groove, the water in the box body 101 can transition in the water diversion groove, and then evenly flow into each water outlet hole 122 through the multiple water diversion notches 127 on the water diversion groove via the diversion part 124, so that each part of the humidifying filter screen 200 can be evenly humidified.

[0066] Specifically, the water diversion groove is cylindrical, four water diversion notches 127 are provided, and the four water diversion notches 127 are evenly distributed along the circumferential direction of the side wall of the water diversion groove. The water in the water diversion groove can flow to the water drainage part in the circumferential direction, making the water drainage more uniform.

[0067] In this embodiment, the raised wall 126 can also play a role in grasping. By grasping the raised wall 126 of the column, the water diversion tray 102 can be rotated, which is convenient for the installation and disassembly of the water diversion tray 102 on the machine base 500. Multiple stripe parts can also be arranged on the outer wall of the raised wall 126 to increase the friction during grasping.

[0068] In an embodiment of the present application, please refer to Figure 6 and Figure 7The water distribution tray 102 has a light guide portion 128 ; a light emitting body 400 is disposed in the base 500 , and light emitted by the light emitting body 400 is emitted from the housing 101 through the light guide portion 128 .

[0069] In this embodiment, the housing 101 may be a wholly transparent structure or a partially transparent structure, as long as the light emitted by the light emitting body 400 can be emitted from the housing 101 .

[0070] In this embodiment, the light emitted by the luminous body 400 can pass through the light guide 128 and be emitted from the box 101, achieving the effect of a night light. It can be understood that the luminous body 400 is located on the side of the light guide 128 away from the box 101 and is sealed in the internal structure of the humidifier, which can play a role in waterproofing and moisture-proofing, thereby increasing the service life of the luminous body 400.

[0071] Specifically, the light guide portion 128 is in a circular shape, and the light-emitting body 400 can be a ring-shaped LED light board that matches the shape of the light guide portion 128. The color of light that can be emitted by the LED light board can be any color such as blue, red, green, etc., or it can be a combination of two or more switchable colors. The specific selection can be made according to the actual needs of the user.

[0072] In one embodiment of the present application, please refer to Figures 3 to 5 The side wall surface of the air outlet housing 300 is at least partially an inclined surface, and the air outlet hole 301 is arranged on the inclined surface. In another embodiment of the present application, the side wall surface of the air outlet housing 300 is at least partially an arc surface, and the air outlet hole 301 is arranged on the arc surface.

[0073] In this embodiment, by setting the air outlet 301 on an inclined surface, the humid air can diffuse faster, reducing the loss of humid air; setting the air outlet 301 on an inclined surface can prevent humid air from being blown toward the user from the front, thereby improving the user experience.

[0074] In one embodiment of the present application, the angle between the axial direction of the air outlet housing 300 and the side wall surface perpendicular to the air outlet housing 300 is in the range of 45 degrees to 60 degrees.

[0075] In this embodiment, Figure 4 As shown, Figure 4 A in the middle represents the angle between the axial direction of the air outlet housing 300 and the side wall surface perpendicular to the air outlet housing 300, that is, the angle at which the humid air is blown out; the angle at which the humid air is blown out is set to 45 degrees to 60 degrees. With this setting, the humid air diffuses fastest and the humid air loss is minimized.

[0076] In one embodiment of the present application, see Figure 2 The air outlet housing 300 is provided with air outlet holes 301 in the circumference thereof.

[0077] In this embodiment, a plurality of air outlets 301 are arranged along the circumferential direction of the air outlet housing 300. The air can pass through the entire area of the annular humidifying filter screen 200, which can make the air outlet area larger and generate humid air more effectively. The humidifying range can surround the four sides of the humidifier, making the humidification more uniform and providing a better user experience.

[0078] In an embodiment of the present application, please refer to Figure 3 and Figure 4 , the fan assembly 600 includes an air outlet hood 601, a wind guide hood 602, a motor 603 and a wind wheel 604. A plurality of air outlets are provided on the air outlet hood 601. One end of the wind guide hood 602 is connected to the air outlet hood 601, and the other end of the wind guide hood 602 is provided with an air inlet, and the air inlet faces the bottom of the machine base 500. The motor 603 is installed on the air outlet hood 601. The wind wheel 604 is connected to the motor 603, and the wind wheel 604 faces the air inlet.

[0079] In this embodiment, by providing the air outlet hood 601 and the wind guide hood 602, an air duct can be formed inside them to connect the air inlet and the air outlet. A very small air speed can generate a large wind force, reducing the noise generated when the fan assembly 600 works. The motor 603 is used to drive the wind wheel 604 to rotate.

[0080] In an embodiment of the present application, please refer to Figure 8 , a plurality of wind guide vanes 611 are provided on the air outlet hood 601, and the plurality of wind guide vanes 611 are arranged at intervals. By providing the wind guide vanes 611, the air blowing towards the humidifying filter screen 200 can be guided, reducing the noise generated when the humidifier works while making the air turn.

[0081] In an embodiment of the present application, please refer to Figure 1 and Figure 3 , the humidifier further includes a water storage tray 700, and the bottom of the humidifying filter screen 200 is placed in the water storage tray 700.

[0082] In this embodiment, by providing the water storage tray 700, the excess water sprayed on the humidifying filter screen 200 can be stored in the water storage tray 700, and this part of the water can maintain a certain humidity of the humidifying filter screen 200, extending the service life of the humidifier.

[0083] In an embodiment of the present application, the depth of the water storage tray 700 is greater than or equal to 15 mm, which can ensure that within an inclination of 10 degrees of the humidifier (the angle between the horizontal placement of the humidifier and the vertical direction), the water in the water storage tray 700 will not overflow, preventing the water from flowing into other components inside the machine base such as the motor or overflowing to the outside of the humidifier, such as the desktop, etc.

[0084] In an embodiment of the present application, please refer toFigure 3 and Figure 4 the highest point of the water storage tray 700 is flush with the highest point of the air outlet cover 601, or the highest point of the water storage tray 700 is lower than the highest point of the air outlet cover 601.

[0085] It can be understood that if the highest point of the water storage tray 700 is higher than the highest point of the air outlet cover 601, the air blown out from the air outlet cover 601 will be blocked by the water storage tray 700, affecting the air inlet area of the humidifying filter screen 200, and further affecting the humidifying capacity. Therefore, in this embodiment, the highest point of the water storage tray 700 is flush with the highest point of the air outlet cover 601, or the highest point of the water storage tray 700 is lower than the highest point of the air outlet cover 601, which can solve this problem and ensure the stability of the humidifying capacity.

[0086] In this embodiment, please refer to Figure 3 , the humidifier further includes a water detection plate 800, which is arranged on the outer wall of the water storage tray 700 and is used to detect the water level in the water storage tray 700. It can be understood that the humidifier may further include a controller (not shown in the figure), and the controller is respectively connected to the water detection plate 800 and the translation driving member 104. When the water level in the water storage tray 700 is lower than the preset value, the water detection plate 800 feeds back the water level signal to the controller, and the controller issues an action instruction to the translation driving member 104 to open the water outlet; when the water level in the water storage tray 700 reaches the preset value, the water detection plate 800 feeds back the water level signal to the controller again, and the controller issues a reverse action instruction to the translation driving member 104 to close the water outlet.

[0087] In an embodiment of the present application, the distance between the outer sidewall of the humidifying filter screen 200 and the inner sidewall of the water storage tray 700 on the side close to the water detection plate 800 is greater than 3 mm.

[0088] In this embodiment, the distance between the outer sidewall of the humidifying filter screen 200 and the inner sidewall of the water storage tray 700 is maintained at more than 3 mm, which can avoid the water on the humidifying filter screen 200 from interfering with the detection of the water level height in the water storage tray 700 by the water detection plate 800, and improve the accuracy of the water level detection in the water storage tray 700. That is, if the humidifying filter screen 200 is too close to the inner sidewall of the water storage tray 700 on the side close to the water detection plate 800, when there is no water in the water storage tray 700 and there is more water on the wet humidifying filter screen 200, it will be misdetected by the water detection plate 800 as there is water in the water storage tray 700.

[0089] In an embodiment of the present application, please refer to Figure 9 , the water detection plate 800 is a capacitive water level sensor, and the capacitive water level sensor includes a chip area 801 and a circuit area 802. The chip area 801 is attached to the outer wall of the water storage tray 700, and the chip area 801 covers the preset water level height range of the water storage tray 700.

[0090] In this embodiment, a capacitive water level sensor is used as the water detection board 800. It is simple and convenient to install and can be directly pasted on the outer wall of the water storage tray 700, and has high detection accuracy. The chip area 801 is attached to the outer wall of the water storage tray 700, which can avoid the existence of a gap between the chip area 801 and the water storage tray 700 and prevent the air in this gap from affecting the water level detection of the water storage tray 700. The chip area 801 covers the preset water level height range of the water storage tray 700, which can ensure the water level detection range of the water storage tray 700. For example, if the preset water level height of the water storage tray 700 is 3 mm, the attachment range of the chip area 801 on the outer wall of the water storage tray 700 should be greater than the interval of 0 - 3 mm. That is, the detection range of the water detection board 800 for the water storage tray 700 is 3 mm upward from the bottom of the water storage tray 700. When the water in the water storage tray 700 is lower than this detection range, the water detection board 800 detects that the water level height of the water storage tray 700 is lower than the preset water level height.

[0091] In an embodiment of the present application, the preset water level height of the water storage tray 700 can be the highest height of the water storage tray 700. The chip area 801 can completely cover the side wall of the water storage tray 700 to achieve more accurate detection of the water level in the water storage tray 700, and can detect the real-time water level height in the water storage tray 700. When the real-time water level height in the water storage tray 700 is lower than the preset water level height, a signal is sent to the control component of the humidifier.

[0092] In another embodiment of the present application, the water detection board 800 can also adopt a reed switch water level sensor, a Hall water level sensor, etc. At this time, the water detection board 800 is arranged inside the water storage tray 700.

[0093] In an embodiment of the present application, at least two water detection boards 800 are arranged, and the adjacent two water detection boards 800 are spaced along the circumferential direction of the water storage tray 700.

[0094] It can be understood that if only one water detection board 800 is arranged, when the water storage tray 700 is tilted, there may be water at one end and no water at the other end of the water storage tray 700; if the water detection board 800 is located at the end of the water storage tray 700 without water, it will be judged that the water level height in the water storage tray 700 is lower than the preset water level height range and the valve 103 is controlled to open, and the water in the box body 101 flows into the water distribution tray 102, resulting in too much water in the water storage tray 700 and then overflowing the water storage tray 700. In this embodiment, by arranging two or more water detection boards 800 and spacing the adjacent two water detection boards 800 along the circumferential direction of the water storage tray 700, the valve 103 of the box body 101 will only open when the water levels detected by all the water detection boards 800 are lower than the preset value, which can prevent the water overflow phenomenon caused by the failure of water level detection during the tilting process of the water storage tray 700.

[0095] In one embodiment of the present application, two adjacent water detection plates 800 are arranged at an interval of 180° along the circumferential direction of the water storage tray 700, which can prevent the water detection plates 800 from misdetecting during the tilting process of the water storage tray 700, so as to avoid the water overflow phenomenon caused by the valve 103 opening to drain water.

[0096] In one embodiment of the present application, please refer to Figure 3 and Figure 4 simultaneously. The humidifier further includes a purification filter screen 900, which is arranged in the machine base 500 and is close to the air inlet hole 511.

[0097] In this embodiment, by arranging the purification filter screen 900, dust and other impurities in the air can be purified, improving the quality of the air entering the humidifier. As a result, fewer air impurities enter the humidification filter screen, and the humidification amount will not be affected. Specifically, the purification filter screen 900 can adopt HEPA (High Efficiency Particulate Air Filter), and HEPA can capture particulate dust and various suspended matters with a size of more than 0.5 μm.

[0098] It can be understood that the machine base 500 is located at the lower end of the air outlet housing 300, the humidification filter screen 200 is located inside the air outlet housing 300, and the purification filter screen 900 is located inside the machine base 500. The humidification filter screen 200 and the purification filter screen 900 can be distributed vertically, achieving separation of dry and wet, ensuring the dryness of the purification filter screen 900, and extending the service life of the purification filter screen 900.

[0099] In this embodiment, the machine base 500 may include a housing 501 and a bottom cover 502. The housing 501 is a cylindrical structure. One end of the housing 501 is connected to the air outlet housing 300, and the other end of the housing 501 is detachably connected to the bottom cover 502. When the humidifier needs to be repaired or maintained, only by opening the bottom cover 502, the internal purification filter screen 900 can be replaced, or the fan assembly 600 can be repaired, and the operation is simple and convenient.

[0100] The working principle of a humidifier provided by the present application:

[0101] When the water in the implementation box body 101 drains, the translation driving member 104 pushes the valve 103 upward, the water outlet opens, and the water in the box body 101 flows along the water distribution tray 102 to the humidification filter screen 200; after the water in the box body 101 has flowed out for a certain period of time (for example: 3 seconds, 5 seconds, etc.), the translation driving member 104 pulls the valve 103 downward (or there is a spring on the valve, and after the translation driving member 104 acts on the valve, the valve automatically resets), the water outlet closes, and the excess water on the humidification filter screen 200 flows into the water storage tray 700 for storage.

[0102] When the humidifier is working, the moisture on the humidifying filter screen 200 gradually decreases, and the water in the water storage tray 700 is absorbed by the humidifying filter screen 200 and decreases. When the water detection board 800 detects that the water level height of the water storage tray 700 is less than the predetermined height, the translation driving member 104 starts again, pushes the valve 103 to move upward, the water outlet opens, and the water in the box body 101 drains for 3 seconds, and works in such a cycle. As Figure 5 shown, Figure 5 the multiple arrows in it schematically show the process of the water flow in the box body 101 flowing to the humidifying filter screen 200.

[0103] When the humidifier is working, the motor 603 drives the wind wheel 604 to rotate and work. The outside air passes through the purification filter screen 900, purifies the pollutants in the air, and then enters the air duct of the fan assembly 600. Under the action of negative pressure, it blows through the humidifying filter screen 200, takes away the moisture on the humidifying filter screen 200, and is blown into the outside air through the air outlet hole 301, so as to realize humidifying the air. As Figure 4 shown, Figure 4 the multiple arrows in it schematically show the air flow direction of the outside air entering from the air inlet hole 511, passing through the fan assembly 600, and then flowing out from the air outlet hole 301.

[0104] The above are only the preferred embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present application shall be included in the protection scope of the present application.
